CROSS-REFERENCE TO RELATED APPLICATIONS

The instant application is a continuation of U.S. patent application Ser. No. 17/190,075, filed Mar. 2, 2021, which claims the benefit of U.S. Provisional Application No. 62/984,068, filed Mar. 2, 2020. The disclosures of the above applications are incorporated herein by reference.

FIELD OF THE INVENTION

The present invention relates to a hard interaction point for a soft panel top assembly moveable between a closed position and multiple open positions.

BACKGROUND OF THE INVENTION

Providing sunroof or convertible tops for sport utility (SUV) type vehicles is desired. The convertible roof can typically be moved between a closed position and at least one open position. When in the closed position, the convertible roof closes off the roof top opening and protects the occupants of the vehicle from various weather conditions. However, there are occasions where the weather is pleasant, and it is desired by the occupants of the vehicle to move the convertible roof to one of its open positions such that the vehicle essentially functions with a sunroof opening, exposing the front cockpit, or further back without a roof where the vehicle interior is exposed to the atmosphere. This allows the occupants of the vehicle to enjoy more favorable weather conditions.

However, current designs for roof tops do not allow for the assembly to open and drop efficiently at the rear of the vehicle, and do not have the option to rotate down and are bulky—making them difficult to move and taking up a lot of space. They also have limited visibility out of the back of the vehicle. Known tops are rather cumbersome to use and take up too much space when in open positions—which is a significant issue due to the poor aerodynamics and wind drag thereby decreasing fuel efficiency while increasing noise from the assembly. Yet another known issue with conventional systems is lowered visibility due to hard rear corners. Theft deterrents are also desired.

Accordingly, there exists a need for a rear hard enclosure interaction that provides improved visibility, security, and theft deterrent and improvement in controlling the motion of the roof top system roof for the vehicle that is capable of movement between a closed position and a plurality of open positions, including dropped down into the cargo hold area of the vehicle.

SUMMARY OF THE INVENTION

The present invention is directed to a panel top assembly adapted for a vehicle, including, a pair of rear side window drip rails operably interfacing with a pair of hard rear side windows, combined with security (e.g., from theft, smash and grab, etc.) by providing the pair of hard rear side windows that wrap around from the side to the back of the vehicle, interface with a rear window, and are adapted to operably connect to the vehicle—forming a rear hard corner with the added benefit of improved visibility. The wrapping pair of hard rear side windows are transparent or clear, including at the hard rear corners, and the rear window is transparent or clear, and the panels interface with each other and are adapted to selectively connect to the vehicle, all of which improves visibility and security and are significant advantages over conventional systems. A pair of hard rear drip rails operably interface to the pair of hard rear side windows.

The hard rear window and pair of hard rear side windows are selectively removable from the vehicle. An articulating portion of the top panel assembly is selectively moveable to operably move rearward and drop down into an open position into the rear cargo area of the vehicle. In addition, the pair of hard rear drip rails rock rearward bringing the back end to rest in the rear cargo area such that the drip rails are at a predetermined angle when the top panel assembly is in the open position.

Further areas of applicability of the present invention will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.
